OSM map is good solution.You can describe on the paper anything e.g. Line, words, arrow, symbol
and illustration.

"OSM sketch" realize such paper mapping on iPhone and
iPad.You can draw on OSM map anything you want to memo anywhere, anytime
without printing beforehand.

Operation is easy and optimized for small screen. Multi touch operation ,scroll and zoom, can be executed also during
"drawing mode" so you can pull out new canvas quickly.To display current location and to zoom in/out map support your mapping
and these function are difficult for paper. This app exchanges these drawn lines into GPX file and uploads to your
OSM account page directly.You can open the GPX file by PC OSM editor(Potlatch2, iD or JOSM) and
edit OSM data based on your lines when you return your home.
